It appears the problem occurred when I tried to load the 3dball example scene included. I have done a complete clean unity install and now it throws all the error when I import com.unity.ml-agents every on time on import. Can anyone at least point me in the right direction?
Log below and the script throwing the file is attached. Thank you!
Basically the release 21 contains a stale version of the 3DBall and other things because Barracuda was replaced by Sentis or something like that but the the update hasn’t been pushed to production, which is the repo you cloned.
